Mariah G21 2012 vs Mariah SC19 Cuddy Cabin 2007 — Same Brand, Different Boat

The Mariah G21 2012 vs Mariah SC19 Cuddy Cabin 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Mariah G21 2012 at 21,4 ft versus Mariah SC19 Cuddy Cabin 2007 at 19,0 ft. Weight tells a clearer story for trailering families: the Mariah SC19 Cuddy Cabin 2007 tips the scales at 325 lbs — 289 lbs less than the Mariah G21 2012 at 36 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 300 hp, the Mariah G21 2012 has a 80-hp advantage over the Mariah SC19 Cuddy Cabin 2007's 220-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 35 gal and 38 gal — so range won't be a tiebreaker here.

Both boats are rated for 1 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Mariah G21 2012 at 21,4 ft is the right call if deck space, comfort, and entertaining are top of your list. The Mariah SC19 Cuddy Cabin 2007 at 19,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

The Mariah G21 2012 is the longer of the two at 21,4 feet overall. The Mariah SC19 Cuddy Cabin 2007 comes in at 19,0 feet, making it roughly 2,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Mariah G21 2012 or the Mariah SC19 Cuddy Cabin 2007?
For trailering, the Mariah G21 2012 has the edge at 36 lbs dry weight versus 325 lbs for the Mariah SC19 Cuddy Cabin 2007. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

The Mariah G21 2012 is rated to a maximum of 300 hp, giving it the larger power ceiling. The Mariah SC19 Cuddy Cabin 2007 tops out at 220 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Mariah G21 2012 is Coast Guard rated for 1 passengers, while the Mariah SC19 Cuddy Cabin 2007 is certified for 1.

The Mariah G21 2012 measures 102" wide, compared to 98" for the Mariah SC19 Cuddy Cabin 2007. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

The Mariah SC19 Cuddy Cabin 2007 has the bigger tank at 38 gallons, versus 35 gallons on the Mariah G21 2012. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
